Zusammenfassung:	The present invention relates to a device for measuring torque transmitted to an output shaft (20) by a harmonic drive gear assembly including a housing (10), a circular spline (16) mounted in the housing, and a flex spline (12) mounted on the output shaft. The device comprises at least one sensor (22a-b) arranged for measuring forces between the circular spline and the housing, and a computing unit configured to receive the measurements from the sensor and, based thereon, to calculate the transmitted torque. L'invention concerne un dispositif permettant de mesurer un couple transmis à un arbre de sortie (20) par un ensemble de transmission à démultiplication harmonique comprenant un boîtier (10), une cannelure circulaire (16) montée dans le boîtier et une cannelure souple (12) montée sur l'arbre de sortie. Le dispositif comprend au moins un capteur (22a-b) agencé pour mesurer les forces entre la cannelure circulaire et le boîtier et une unité de calcul conçue pour recevoir les mesures provenant du capteur et, sur la base de celle-ci, pour calculer le couple transmis.
