howdi...yes allen keys can work on the torx screw but there are chances to thread them and destroy it....For the sake of doing it properly get hands on torx screw otherwise can play doggy like kriss did and use allen keys...in the end the end result will be the same...
charles my advice will be try to use allen keys (like what kriss did) and if it doesnt work (which is unlikely) let me know ill lend you the torx screw driver for you to adjust the wing....
