Beschreibung
Zusammenfassung:	A torque sensor that includes a sensor housing (10), a sensor input member (12) at least partially received in the sensor housing (10), a sensor output member (14) at least partially received in the sensor housing (10), a torsionally resilient coupling member (16) that couples the sensor input member (12) to the sensor output member (14) and an optical sensor system (18) that includes a light source (90), one or more encoders (94,96) and one or more optical sensors (98). The encoder or encoders (94,96) periodically transmit light between the light source (90) and the at least one optical sensor (98) based on an amount of relative rotation between the sensor input member (42) and the sensor output member (44).
