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.

These terms are all defined quite specifically. You can find them in any
physics textbook. Look them up and compare them to your statements. You're
just digging yourself in deeper.
