The factory springs for the door handle have square cut ends, like the "left" end of your spring. The "right" end in your photo does appears to have a fracture failure. If that end of the spring is too short to engage the molded pin on the handle mechanism or the inner portion of the handle mechanism it will not work.
Relative to replacement, I suggest looking at an industrial supply catalog from Grainger or McMaster Carr for a 180 degree torsion spring and match the size to the one you have.
