Narrative:

After takeoff, flight to tri experienced a 45%-55% decrease in torque on the left engine. The first officer was PF. The torque came back to normal within 2-3 seconds. I informed ATC that we would be returning to land. While performing the after takeoff checks, the left generator failed. I completed the after takeoff checks, raising the flaps at this time. A flap overspd message was observed. The left generator was restored using company procedures. We circled and landed following normal company procedures. Upon returning to the gate, I wrote up the left engine and flap overspd items. The flap overspd was caused by the distraction of the situation (engine, generator, radio communication). The safety of the flight was never compromised.
