Abstract
A torque measurement flexplate (20) includes a substantially planar body (54) which defines a plurality of circumferentially distributed axial through apertures (22), a radial web (24) extending between each pair of adjacent axial apertures (22). The flexplate (20) further defines a plurality of circumferentially distributed axial outer fastening holes (26) for attachment to an output member. The flexplate (20) includes a strain sensor (28) for measuring the shear strain field on the flexplate (20). The flexplate (20) defines a recess (30) in which the strain sensor (28) is located, the recess (30) being defined in an axial surface (32) of one of the radial webs (24) such that, in use, the sensor (28) lies at least proximate to one of the local neutral axes (34) relating to one of a plurality of unwanted strains (36) to which the flexplate (20) is subject in use.
