Abstract
A control coupling in which an enclosure houses first and second sets of mutually interleaved elements in a viscous liquid. The first and second sets of elements are arranged for rotation about a common axis and for driving connection with first and second rotatable members respectively. A clutch is provided outside the enclosure and resilient means are arranged to urge the clutch into a disengaged state. A pressure responsive means which is in communication with the enclosure is arranged to engage the clutch against the action of the resilient means when the pressure in the liquid in the enclosure attains a predetermined level.
