Abstract
A method of monitoring torque in a drive transmission incorporating a friction clutch assembly having a two part rotatable drive transmitting member the two parts of which are relatively movable against the action of damper springs comprising monitoring the extent of the relative movement of said two parts (16, 17) of said drive transmitting member. The invention also resides in a friction clutch assembly having a two part, rotatable, drive transmitting member, the two parts being movable relative to one another against the action of damper springs, the clutch including a plurality of angularly spaced reference teeth on each part of said two part member respectively and a sensor relative to which said two part member rotates, said sensor monitoring said teeth and in use producing, at a plurality of points in each revolution of the two part member, an output representative of the relative positions of said parts of said two part member.
