Uh huh. And would you care to comment on exactly how that statement is
wrong? Torque is a turning moment that defines the force applied to a shaft
in order to do work. Without torque the shaft cannot turn, work cannot be
done.

Although to be a spoilsport, no work is done by a shaft
that is providing a torque, but is not turning. A wrench
on a stuck bolt, for example.

Torque is still RXF but because the angular velocity is
zero, work being done is zero.
