Claim:
1. A sensor for measuring the amount of torque transmitted through a coupled shaft that is comprised of a first section and a second section in which: the first section is mechanically fixed to the second to form a single assembly wherein said assembly permits relative rotation between the two sections under the influence of a torque with said first section having protruding non-magnetic tabs and said second section having ferromagnetic flexures that cooperate together so as to transfer torque from the first section to the second section in which said torque produces deflection of a flexure beam to which at least one permanent magnet is attached such that said deflection will reduce an air gap between the permanent magnet and a ferromagnetic stationary sensing ring onto which is embedded an array of magnetic field sensors with said magnetic field sensors capable of detecting changes in the magnetic field flowing through said sensing ring.
