Abstract
An angular signalling device comprising a housing, a torque transmitting unit extending through the housing, first and second rotors fixed to respective first and second unit regions for rotation relative to the housing, an output member supported for movement with respect to the housing and the rotors, a transmission for transmitting drive between the output member and the first rotor so that the output member movement bears a predetermined relationship to movement of the first rotor, a first angular displacement signal generator comprising a first signal element fixed with respect to the output member and the second signal element fixed with respect to the housing, the signal elements coupled together and relatively moveable to produce a first angular displacement signal whose value changes in relation to the extent of the relative angular movement between the first rotor and the housing, and a second angular displacement signal generator comprising third and fourth signal elements coupled together to produce a second angular displacement signal having a value which varies in relation to the angular displacement between the first and second rotors.
