An integrated torque limiter/no-back device (36) for use in an actuator (20) with an input shaft (30), an output (34) and gear reduction (32). The device includes an input ramp (38) to receive torque from the input shaft (30); a combined ramp (40) to transfer torque; an output ramp (42) to transfer torque to the gear reduction (32); one or more balls (46; 48) between the input ramp (38) and the combined ramp (40) and between the combined ramp (40) and the output ramp (42) to transfer torque; and a brake (44; 45) for causing torque to be grounded and for preventing backdriving of the input shaft by preventing movement of one or more of the input ramp (38), the combined ramp (40) and the output ramp (42) when a torque threshold has been met. The input ramp and the output ramp are one of a no-back ramp (42) and a torque limiter ramp (38), respectively, and the device (36) also includes a pin (50) between the combined ramp (40) and one or more of the no-back ramp (42) and the gear reduction (32) for transferring torque.
