A torsion member (12) has opposing protruding end elements (4, 6) configured for transmitting torque therebetween. A first contact mechanism (20, 26) is mounted to a surface (10) of one end (4) of the torsion member (12). The first contact mechanism includes a movable contact (26') disposed between the end elements (4, 6) of the torsion member. A second contact mechanism (18, 28) is mounted to a surface (11) of the other end element (6) of the torsion member (12). The second contact mechanism includes a movable contact (28') disposed near the first contact (26'). The first contact (26') and second contact (28') move toward each other whenever torsion is applied to the torsion member (12). Means (30, 40) are provided for changing the distance between the first and second contacts (26', 28'), and for producing a signal whenever the first and second contacts touch.
