Andoyer variables are well known for the study of the rigid body dynamics. But these variables were derived by Andoyer through a procedure that can be also used to obtain the Delaunay variables of the Kepler problem in a direct way, without the use of Hamilton-Jacobi theory or non intuitive generating functions.
