In the towing hitch (10a), it is provided that it has a rotation drive device (31a) which has a rotation drive body (30a) protruding in a contact position (K) in front of the ball surface (23), which is rotatably mounted relative to the ball surface (23) on the coupling device (11a) and has a rotation drive surface (76) designed for a friction-locked and/or form-locked rotation drive contact with the coupling socket (18), and that it has a sensor arrangement (40) for detecting a rotation angle (34) of the rotation drive body (30a) relative to the ball mount.",
