ABSTRACT A control coupling, particularly for use with a differential gearing, the coupling including an enclosure containing a viscous liquid and first and second mutually inter- leaved sets of annular plates arranged for rotation about a common axis within the enclosure. The first set of plates are arranged to be connected with a first rotatable member and the second set of plates being arranged to be connected with a second rotatable member, and the plates of at least one set are free to move in directions parallel to the common axis. The enclosure incorporates an element which is movable independently of the plates in order to vary the volume of the enclosure and spring are provided to urge the element towards a limit position in which the volume of the enclosure is at a minimum. The element is displaceable against the spring, in response to increases in liquid pressure in the enclosure, to increase the volume of the enclosure.
