I would like to differ a little bit.  How can torque be force when force
is already only part of the equation?  Torque is a quantity expressing
the effectiveness of a force to change the net rate of rotation of a
body. It is equal to the product of the force acting on the body and the
distance from its point of application to the axis around which the body
is free to rotate. 

Phil is correct, torque does not require motion, hence the valid
expression "stall torque" or for an electric motor "locked rotor
torque."
