The measurement of how much force is needed to make an object rotate around an axis: Car engines with high torque can produce a great deal of force to make a car go quickly.

The measure of the pppropensity or tendency of a force to create rotation or torsion around an axis: A variable-torque load is exemplified by a load that requires low torque at low speeds and increasing torque as the speed is increased, with very high torque being required at high speeds.
