Turbine engine module with electric machine

An assembly for a turbine engine, comprising:

• a turbine engine shaft configured to rotate about a rotational axis;
• a turbine engine module including an electric machine and a gearbox, the electric machine including an electric machine rotor and an electric machine stator, the gearbox including a rotating structure coupled to the electric machine rotor, and the rotating structure configured to rotate about the rotational axis;
• a rotating coupler coupled to the turbine engine shaft by a coupler-shaft spline connection, and the rotating coupler coupled to the rotating structure by a coupler-gearbox spline connection;
• and
• a seal assembly including a rotating seal land and a stationary seal element, the rotating seal land mounted onto the rotating coupler, and the stationary seal element sealingly engaging the rotating seal land.
