ABSTRACT:
A rotary coupling for connecting a control device housing to a support arm or an elbow of a support arm system, having a rotating ring fixedly connected to the control device housing and partially rotatable in relation to a coupling piece which is connected to the support arm or the elbow. For equalization of tolerances caused by insufficient twist rigidity of the support arm system, the invention provides that the coupling piece forms a peripheral bearing ring which is convexly arched outwardly and is received in and supported by two shell rings. The shell rings are connected to each other and have concavely arched bearing surfaces. The shell rings are rigidly mounted on the bearing ring of the coupling piece by a clamping cheek. The rotating ring is rotatably maintained on the shell rings by a support ring which is connected to the shell rings.
