Abstract
A torque transfer limiting arrangement for a rotational drive shaft. The arrangement includes a torque sensing device for sensing torque within the drive shaft and outputing a signal indicative of the sensed torque. A braking device of the arrangement is actuatable for stopping the drive shaft from rotating. The arrangement also includes a portion for electrically causing operation of the braking device responsive to the signal indicative of the sensed torque above a predetermined value. In one example, the portion for electrically causing operation of the braking device includes a processor. In one example, the rotational drive shaft is part of an aircraft flap actuator system.
