Embodiments of the present invention generally relate to a torque sub for use with a top drive. In one embodiment a method of connecting threaded tubular members for use in a wellbore is disclosed. The method includes operating a top drive, thereby rotating a first threaded tubular member relative to a second threaded tubular member; measuring a torque exerted on the first tubular member by the top drive, wherein the torque is measured using a torque shaft rotationally coupled to the top drive and the first tubular, the torque shaft having a strain gage disposed thereon; wirelessly transmitting the measured torque from the torque shaft to a stationary interface; measuring rotation of the first tubular member; determining acceptability of the threaded connection; and stopping rotation of the first threaded member when the threaded connection is complete or if the threaded connection is unacceptable.
