Torque is a measure of rotational strength, and is given by the force applied (in the tangential direction) multiplied by the distance from the rotational center that it is applied from (i.e. the amount of leverage).
High torque indicates a turning motion that is very difficult to stop, but it does not say anything about the rate of rotation. A fast rotating object may be under a low torque, or a slow rotating object a high torque.
