A pneumatic collet assembly has a housing, a piston, a collet, and ball bearings. The piston is disposed within the housing. A bore within the piston receives the collet. The collet has a base and fingers. The fingers of the collet define a center channel or bore configured to receive a torsion bar. The central channel extends along a longitudinal axis. The ball bearings are disposed between the piston and the fingers of the collet. The piston is configured to move between a first position along the longitudinal axis and a second position along the longitudinal axis in response to pressure changes within the housing. The piston increases force against the ball bearings to urge the fingers of the collet against the torsion bar to clamp the torsion bar.
