An apparatus for detecting and measuring torque applied about the central longitudinal axis thereof, comprising: (a) a first radially extending member; (b) a second radially extending member, said second radially extending member being longitudinally spaced from said first radially extending member;

An apparatus for detecting and measuring torque applied about the central longitudinal axis thereof, comprising: (a) a first radially extending member; (b) a second radially extending member, said second radially extending member being longitudinally spaced from said first radially extending member; (c) a plurality of circumferentially symmetrically spaced elongate, longitudinally extending members connecting said first and second radially extending members comprising: (i) a first elongate longitudinally extending member having a first surface portion facing in a first circumferential direction and a second surface portion facing in a second circumferential direction opposite said first circumferential direction and having a first end portion fixedly attached to said first radially extending member and having a second end portion fixedly attached to said second radially extending member; and (ii) a second elongate longitudinally extending member having a first surface portion facing in said first circumferential direction and a second surface portion facing in said second circumferential direction and having a first end fixedly attached to said first radially extending member and having a second end fixedly attached to said second radially extending member; (d) first and second strain detecting means operably associated with at least one end portion of at least one of said first and second surface portions of said first elongate member for generating a first and a second strain detection signal indicative of the strain in said associated portions of said first elongate member; (e) third and fourth strain detecting means operably associated with at least one end portion of at least one of said first and second surface portions of said second elongate member for generating a third and a fourth strain detection signal indicative of the strain in said associated portions of said second elongate member; and (f) data processing means for receiving and processing said first, second, third and fourth strain detection signals for determining the amount of torque being applied to said apparatus about said central longitudinal axis thereof and for generating a torque signal indicative thereof.
