1. A torque sensing arrangement for an engine transmission connection including an engine crankshaft and a torque converter housing, said torque sensing arrangement comprising:

  • a driving hub connected to said engine crankshaft to be rotated thereby;

    a flex plate fixed to said driving hub;

    a circumferential series of stop elements fixed to said torque converter housing and passing through respective arcuate slots in said flex plate, limiting relative rotation between said torque converter housing and said flex plate to a predetermined extent;

    a series of radially extending blade springs fixedly anchored at their inner ends to a respective one of a series of slots in said driving hub;

    a circumferential series of pairs of spaced elements fixed to a driving disc connected to said torque converter housing, each of said blade springs having a radially outward free end passing between pairs of said spaced elements to be captured therebetween; and

    sensor means for detecting the extent of relative angular movement between said flex plate and said torque converter housing and generating signals corresponding thereto.
