摘要： 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).
