Abstract
The torque sensor comprises first (11) and second rotary structures coupled respectively for rotation to first (5) and second (4) coaxial rotary members mutually coupled by a dead-travel resilient coupling (6), the rotary structures having adjacent zones each formed with a series of angularly spaced optical windows (13, 14) arranged to cross a light path, two corresponding windows belonging to each series being in partial overlapping relationship in the light path when the rotary members are in a relative neutral position.
