A change-over coupling (1) for robot-guided vehicles (3) has a plurality of media couplings (11, 12) and has coupling parts (4, 5) having basic supports (6, 7), media coupling supports (13, 14) and a coupling mechanism (8), and also peripherally arranged interfaces (16) having a fitting element for the media couplings (11, 12). The interfaces (16) have a plurality of fitting elements (19, 19′, 20, 20′), which act in a plurality of different directions or axes and which are arranged preferably at a periphery, in particular on a circumference of a disc-like or annular basic support (6, 7).
