Narrative:
This morning while departing we experienced an engine roll back. The first officer ran the runway item checklist as I taxied out onto [the] runway. As I started to apply takeoff power all engine indications were normal. Upon reaching close to firewall [I] noticed we [were] not at the usual torque numbers. I then verified the throttle and advanced it full forward. At this point the indications went back to normal and we had reached vr. We rotated and I instructed [the first officer] to watch our torque-meter and notify [me] if it changed at all; and if it did we would be making an immediate turn back to [the] runway. Shortly after passing through 500 ft AGL and in a left turn to a 090 heading he stated that indeed the torque was rolling back. As previously briefed I executed a left turn back to [the runway] and landed without issue.
