Cams don't twist, they break. The gear would strip or the little drive shaft would shear well before the cam would ever get damaged!
I agree I thought about that but cams don’t twist they are so hard they are brittle they Either wear lobes down or they break. And I thought maybe it shared a key in the keyway so that’s why I pulled the timing cover off to check those but they were still aligned.
