JUST AFTER TAKEOFF, THE RED CAUTION LIGHT FLASHED AND PILOT NOTED THE TORQUE INDICATION CLIMBED TO THE GAUGE HIGH SIDE STOP. NO OTHER INDICATIONS OR ENGINE SURGES WERE NOTED. PILOT DECLARED AN EMERGENCY AND LANDED ON THE SAME RUNWAY WITHOUT INCIDENT. PERFORMED A VISUAL INSPECTION OF TORQUE TRANSDUCER AND CONNECTOR WITH NO OBVIOUS SIGN OF DAMAGE OR LOOSENESS. DOWNLOADED THE TREND ANALYSIS INFORMATION AND SENT IN FOR REVIEW. AFTER REVIEW, THE DATA CONFIRMED THE EVENT TO BE A TORQUE INDICATION ISSUE. ALL OTHER ENGINE PARAMETERS WERE WITHIN NORMAL TOLERANCES. PERFOMED THREE SEPARATE ENGINE RUNS AT TAKE OFF POWER AND COULD NOT DUPLICATE PREVIOUS INDICATION. AIRCRAFT RETURNED TO SERVICE.
