A vertical movement capacitive torque sensor for a rotating shaft such as the steering column of an automobile includes dielectric vanes interposed between capacitor plates which are moveable proportional to the angular displacement of two shaft portions which are linked by a torsion bar or concentric inner and outer shaft portions, the vanes move in a radial direction perpendicular to the shaft axis. Concentric capacitor rings are provided so that a bridge circuit can easily indicate differential capacitance which is proportional to clockwise or counter-clockwise torque.
