Abstract: A clamp coupling has a slotted clamping ring seated on a first rotatable part. A clamping screw is arranged in the clamping ring and acts on the clamping ring to elastically spread the clamping ring apart and contract the clamping ring depending on the turning direction of the clamping screw. The first rotatable part has axially oriented slots that extend up to a free end face of the first rotatable part and that separate coupling segments of the first rotatable part from each other. The slots are arranged in an area surrounded by the clamping ring. The coupling segments receive a second rotating part and are clamped by the clamping ring on the second rotating part. A follower part is arranged on the clamping ring and in a spreading-apart direction of the clamping ring is fixedly connected with at least one of the coupling segments.
