Aircraft
In compliance with the SID we were climbing to the assigned altitude departing ZZZ on the ZZZZZ departure. We were assigned a new heading to proceed northwest bound. The Captain set the new heading then we quickly noticed that the autopilot was not engaging. The Captain was able to use the Touch Control Steering to initiate the turn to the assigned heading. Shortly after; the aircraft started a sudden left roll which was unexpected. This was when we attempted to disengage the autopilot. The Captain asked me to inform ATC that we needed to return back to ZZZ. We were able to regain directional control. We landed at ZZZ; VFR conditions with no issues.
