Abstract
A device, system, and method for measuring torque, comprising an acoustic wave device removably attached to a rotatable shaft by a variably-shaped retainer, wherein removal of the acoustic wave device with the variably-shaped retainer facilitates servicing and replacement of the torque measurement device. The acoustic wave device can be removably attached to the rotatable shaft by using one or more connectors. Other acoustic wave devices such as acoustic wave resonators, surface acoustic wave delay lines, surface acoustic wave filters, and surface transverse waves can also be removably attached to the rotatable shaft to measure torque.
