1. A fluid coupling comprising:
two coupling halves which are releasably connected on their coupling sides, each coupling half having a coupling housing, being equipped with a rotary valve, being aligned along a coupling axis, and being formed correspondingly similar to each other in such a manner that each of said rotary valves has a rotary body mounted on the coupling housing so as to be rotatable about a valve axis, which is directed transversely to the coupling axis, and a fluid passage which traverses said rotary body, said fluid passage closing and opening the rotary valve depending on controllable rotational positions of the rotary body about the valve axis, in that a drive device, which is associated in each case with of the rotary bodies for controlling rotational position, is arranged on each of said coupling halves, in that each of said coupling halves is equipped with a coupling means which connects the coupling halves, it being possible for the connection to be established releasably for uncoupling and conversely for coupling by relative rotational movement of the coupling halves about the coupling axis, and in that the coupling halves have securing means which block the relative rotational movement for securing the connection of the coupling halves when at least one rotary valve is open and which secure the closure of the two rotary valves for disconnecting and correspondingly for connecting the coupling halves;
wherein the drive device, which is arranged separately on each of the coupling halves halves, has a drive shaft which is associated in each case with a valve shaft of the rotary body of the rotary valve of the other coupling half, whereby in each case, a locking connection is configured which, when the coupling halves are connected to each other, connects the respective drive shaft on the one coupling half to the respective valve shaft on the other coupling half in a non-rotatable and releasable manner such that the rotational position of the rotary body of the other coupling half is controllable thereby and the relative rotational movement of the coupling halves about the coupling axis is blocked but the relative rotational movement when the rotary valves are closed is permitted.
