Abstract
A viscous shear coupling has housing and hub parts (20 and 22) with interleaved sets of plates (35, 36, 37), the set of plates carried by the housing part being in two sub-sets (35 and 36), the plates (36) of one sub-set being rotationally fast with the housing part and the plates (35) of the other sub-set being capable of limited relative rotation to the housing part and the plates of the other sub-set; plates of the first set carry projections (50, 52) so that upon said relative rotation the spacing of the plates is varied thus to control the torque transmitted by the coupling.
