First Officer reported loss of aircraft control and autopilot disengagement due to severe turbulence. Pilot performed upset recovery and flight continued.

Narrative

We were at cruise and everything had been going normal at FL 410. It was smooth air the entire flight and ATC had been telling us it would continue. We were cruising at .78 with good margin below the red tape when all the sudden we hit severe turbulence. I looked down and saw the speed tape trending toward and overspeed so I pulled the thrust levers back; at that point I also noticed we were climbing at a very fast rate and the airspeed was still trending in the upward direction. The aircraft was also put into roughly a 25 degree bank. The autopilot automatically kicked off just before I was disengaging it and the throttles myself. At this point we were at FL 415 and the clacker was going off due to the overspeed. I performed the upset recovery procedure and brought the plane back down to 410 and back to a speed of .76. I had never experienced anything like that in my career and the Captain also said he hadn't. It only lasted a few seconds and then the air was back to being smooth the remainder of the flight. We advised ATC of what happened. No one was up during this and no one was injured. We landed with no other issues.Location: Just past ZPLEN on the TEEKY arrival.Suggestions: Our Company was ahead of us by like 20 miles or so at the same altitude and had no issues. We seemed to be the only aircraft to encounter that at that altitude that might. I would say the only thing I can think of would be to not operate the aircraft at the max operating altitude to give a buffer for if this were to happen again; the aircraft doesn't go above that altitude.
