Aircraft
The flight was departing on an IFR flight plan; the weather was VFR. On initial climb out the left torque meter was showing a lower torque than the right side. I advised Departure of the impending issue and elected to return. I applied more power to the left engine and the torque came up and then decreased; and then the gauge displayed a significant loss of torque. With some asymmetric thrust occurring at the same time; I decided to feather the propeller and returned for a successful no-event landing.
The BE20 pilot returned to his departure airport after the left engine torque indication decreased and asymmetric thrust increased. He landed uneventfully with the engine feathered.
