    At least with a lever can the magnitude of torque be considered the equivalent of energy or work?
    Since the formula l*F*sin(theta) could equal F*d?

    No. Torque and work have the same units of measurement, but they aren't the same.

    To amplify what Harold said, while torque and energy have the same units they are quite different.

    Energy is a scalar, the dot product of the force and displacement vectors. Torque is a vector, the cross product of the force vector and the moment arm vector.
