    "14. The coupled assembly of claim 9, further comprising a securing element that interferes with or abuts a feature of the bottom plate to prevent rotation of the outer ring from the first position.",
    "15. A method of coupling and uncoupling a first device and a second device, comprising: inserting, along a connection axis, a bayonet of the first device into a slot of a coupling assembly, the coupling assembly being secured to the second device, the coupling having a locking arm that is axially aligned with the slot and a biasing arm in a region that is radially offset from the locking arm; and rotating, about the connection axis, the first and second devices with respect to one another to move the bayonet from the slot to the region, the locking arm having a normal position that interferes with movement of the bayonet from the region to the slot, the biasing arm applying a biasing force along the connection axis on the bayonet when the locking arm is in the normal position interfering with movement of the bayonet from the region to the slot.",
    "16. The method of claim 15, wherein the rotating of the first and second devices with respect to one another comprises rotating between 5 and 45 degrees.",
    "17. The method of claim 15, further comprising: rotating, about the connection axis, an outer ring of the coupling to move the locking arm from the normal position; rotating, about the connection axis, the first and second devices with respect to one another to move the bayonet from the region to the slot; and withdrawing, along the connection axis, the bayonet from the slot.",
    "18. The method of claim 17, wherein the rotating of the outer ring comprises rotating between 5 and 45 degrees.",
    "19. A coupling assembly for a first device having a bayonet, comprising: a top plate having a slot along a connection axis, the slot being configured to receive the bayonet; a bottom plate having a locking arm in axial alignment with the slot and a biasing arm in a region that is radially offset from the locking arm; first fasteners securing the top and bottom plates to one another; an outer ring and first fasteners securing the top and bottom plates to one another so that the outer ring is rotatable about the connection axis between a first position and a second position; and a securing element that interferes with or abuts a feature of the bottom plate to prevent rotation of the outer ring from the first position, wherein the region is configured to receive the bayonet, when in a locked position, with the locking arm preventing the bayonet, by interference with locking arm, from rotating about the connection axis back into alignment with the slot and with the biasing arm preventing the bayonet, by interference with biasing arm, from being withdrawn axially along the connection axis.",

  "description_excerpt": "1. Field of the Disclosure The present disclosure generally relates to coupling assemblies. More particularly, the present disclosure relates to coupling assemblies that are configured to form a quick mechanical connection between two devices in a manner that also forms a seal therebetween. In some embodiments, the coupling assemblies of the present disclosure are particularly suited for use in connecting devices in the form of a radio and an antenna to one another. 2. Description of Related Art Coupling assemblies are known. Such assemblies have found use mechanically connecting two devices to one another where the devices can include, but are not limited to, mechanical devices, electrical devices, optical devices, hydraulic devices, fluidic devices, other devices, and combinations thereof. In some instances, it is desired for the coupling assembly to form the mechanical connection in rapid or easy to form manner. These so called “quick” coupling assemblies have taken a variety of configurations, but are generally configured to allow the connection of two devices without the use of tools, with a minimum number of manual manipulations, and often with the use of only a single hand. In other instances, it is desired for the coupling assembly to form a seal between the devices in addition to the mechanical connection.\n\nFor example, the connection of an antenna and a radio (e.g., transmitter and/or receiver) to one another often requires an easy to assemble mechanical connection between the antenna and the radio that, in some instances, forms a seal.",
