A failsafe electro-mechanical actuator (130), the actuator having: an output shaft (250) having a first and second ends (250A, 250B) spaced apart from each other along a shaft axis, and outwardly facing helical grooves (360) formed along the first end; a motor shaft (180) surrounding the output shaft (250); a harmonic drive (270) between the motor and output shafts that transfers motion between these shafts in a first mode of operation; ball bearings (200D) seated at the first end (180A) of the motor shaft (180) and project inwardly from the motor shaft; in the first mode of operation: the ball bearings (200D) are disengaged from the output shaft (250) and the output shaft rotates with the motor shaft (180), and in a second mode of operation, the motor shaft axially moves toward the first end of the output shaft; the motor shaft is rotationally fixed; and the ball bearings engage the helical grooves in the output shaft, whereby the output shaft rotates.
