ABSTRACT:
A counter torque tube connection which couples a first tube and a second tube in turbine engine. The connection first tube includes a male connector component having a ballnose. The ballnose includes a plurality of protrusions. The connection second tube includes a female connector component having a ferrule end fitting sized to receive the ballnose. The female connection component includes a plurality of protrusions that interfit with the ballnose protrusions. The tubes are coupled by extended a nut over the female component and coupling the nut to the male component. The interfitting protrusions prevent torsional loads applied to the tubes from being transmitted to the nut so that the nut remains secured.
