Human Factors; Weather
At approximately XA:10; I encountered severe turbulence/wind shear and the autopilot disengaged as I was beginning a descent from 33000 ft. to ZZZZZ intersection on the ZZZZZ1 arrival into ZZZ1. I temporarily lost control [of] the aircraft as it began a hard; left turn of almost 90 degrees before I was able to regain control and return to my assigned route. On board radar showed no precipitation ahead at the time.
C510 pilot reported a temporary loss of aircraft control due to a severe turbulence/wind shear encounter during initial descent.
