An authority limiter includes an input shaft clutched to an output shaft. The output shaft is geared to a motor. Opto-sensors provide control signals to a current source supplying power to the motor. Different amounts of opposing torque are applied by the motor dependent upon the positioning of a disc, mechanically attached to the output shaft, effecting the optical path in the opto-sensors. In another embodiment, the opto-sensor control is replaced by an electro-mechanical mechanism which senses various thresholds corresponding to angular positions of the coupled input and output shafts.

In combination with an autopilot trasnfer device, an authority limiter comprising: a. an input shaft which is normally free to rotate in either direction; b. a motor gear output shaft; c. an electromagnetic clutch used to couple the input shaft to the motor gear output shaft; d. a torque motor geared to said output shaft; e. An obtruding disc attached to the motor gear output shaft, said obtruding disc having at least three arcuate cut-out portions therethrough respectively indicative of a null agular position of said output shaft and at least two predetermined degrees of permissible angular deviation in either direction from said null position by said output shaft; f. at least three stationary opto sensors activated by the presence or absence of said cut-out portions of said obtruding disc and producing outputs respectively representative of the direction of angular deviation by said output shaft from said null position and of any angular deviation exceeding either of said two predetermined degrees of angular deviation; and g. an electronic circuit means for controllably applying at least two scheduled currents, dependent upon the outputs of said opto sensors, to said torque motor to generate two corresponding scheduled opposing torques in either opposing direction on said output shaft when the angular deviation thereof exceeds a corresponding predetermined degree of angular deviation.
