If you have a torsion spring with a known spring constant, it is possible to deduce how much torque is being applied by how many degrees the spring has twisted. But that is not the same thing as saying torque is expressed as degrees any more than the power of a car's engine may be reflected in how many miles an hour the car can go, but power of the car's engine can not be expressed in miles per hour.
Torque can be thought of as the amount of oomph you put into twisting something around an axis of rotation. Degrees is how much you've succeeded in twisting something about an axis of rotation.
It is never good to try to learn basic concepts in physics using English units because English units try to shoehorn sharp and precise concepts into terminology conceived of during an earlier age of nebulous confusion, when weight, mass, and even force seemed much the same thing.
If you use metric units it becomes much more clear what is going on. Torque in Metric is Newton-Meters. Newtons is a unit of force. Torque of one Newton-meter is the amount of twisting oomph that occurs at one end of a 1 meter lever arm when you apply a force of one Newtons on the other end of the lever arm. If you apply twice the force, you get the same ommph with half the lever arm length. Mass is the amount of resistance stuff has to changes in the direction and speed of its motion. The effort to change the direction and speed of the motion is force. Unit of mass is Kilograms, and unit of force is Newtons. Weight is the force required to resist changes in direction and speed of motion of object under gravity. Since weight is force, units of weight is also Newtons.
That's a whole lot of typing to prove you don't know what you are talking about.
Here's a link to the tool you say shouldn't exist.

Is that little enough typing for you?
