Yes, but isn't that what WORK/ENERGY is?

Work is force acting though a distance: W = F(dot)d. With torque, the
force is perpendicular to the distance vector , so when you compute the
dot product you get zero.

Torque, like distance and force, is a vector quantity while energy
(work) is a scalar. To compute torque, you take the vector cross
product of force and position vector: T = F x d. This gives a vector,
unlike the dot product above which gives a scalar.

To say a vector (torque) is equal to a scalar (energy) is like saying
Wednesday is equal to cheese. It makes no sense.

Yeah, everybody know Wednesday is Prince spaghetti (day).
