Apparatus and associated methods relate to an anti-rotation device (ARD) including a cylindrical ring extending along a longitudinal axis, the ring including proximal and distal faces. In an illustrative example, the ring may include proximal coupling members extending from the proximal face insertably engaging with mating recesses within a connector-disk. The ring may include distal coupling members extending from the distal face insertably engaging with mating recesses within a body-assembly, for example. The coupling members may extend, for example, parallel to the longitudinal axis. The ARD may be captured between the connector-disk and the body-assembly and may be retained by a proximal twist-lock cap screwably engaged with the body-assembly, such that relative rotational motion between the connector-disk and the body-assembly is substantially restricted, for example. Various ARDs may substantially restrict relative rotational motion between connector-disks and body-assemblies advantageously mitigating disconnection of wiring harnesses in circular connector applications.
