Abstract
A method is provided for measuring torque in a shaft of a drive line including a disc coupling component such as a flexplateor a flanged coupling, as well as a drive coupling system for carrying out the method. The disc coupling componentis connected between a drive inputand a drive output so that all torque transmitted between the input and output passes through said component. The disc coupling componenthas a radially extending portion, which may include a plurality of spokes, to which is attached a SAW based strain sensor which communicates with a stationary couplerfastened to an engine blockfor wireless transmission of data from the sensor, the strain sensor measuring the strain in the disc coupling componentfrom which the torque carried in the input shaftmay be calculated.
