    • The present invention concerns an arrangement (20) for measuring torque in a transmission system with a quill shaft (2) coaxially inside a bore of a driveshaft (3), coaxially supported in a sleeve (6). The quill shaft is fixed to the driveshaft (3) at a first end and to the sleeve (6) at a second end, whereby a load applied to the driveshaft (3) results in torsion of the quill shaft (2) and a torsional displacement of the driveshaft (3) in the sleeve (6). The arrangement includes a measuring surface (221) extending circumferentially along a segment angle of the transmission system and the measuring surface extends with a varying distance in an axial direction along at least a part of the segment angle at one of the sleeve (6) and the driveshaft (3). A gap sensing element (21) is provided for measuring the size of a gap between the gap sensing element (21) and the measuring surface (221) at the other of the sleeve (6) and the driveshaft (3).

    • A transducer for measuring torque in a rotating shaft at least partially surrounded by a fixed housing. The transducer comprises an optical displacement sensing means, an optical transmission means, and an optical-electric converter means. The optical displacement sensing means residing on the shaft and modulating a light signal input to provide a light signal output relating to the magnitude of torque. The light signal output communicated to the optical-electric converter means via the optical transmission means. The optical transmission means comprising an optical clock spring, the optical-electric converter means either mounted to the housing or external to the housing. The optical clock spring comprising one or more flexible fiber optical cables, each cable arranged to be of sufficient length to allow the measurement of the magnitude of torque over a predetermined angular range of rotation of the shaft and the optical-electric converter means thereby providing an electrical output signal relating to the magnitude of the torque in the shaft.
