fbx made of seperate pieces not importing correctly.

So i have my model made up of separate pieces. The arms the head the torso and coat. It looks good in blender but when i export into unity this happens. the torso is off angle and theres all these other animations. Obviously nothign looks right !

I did not name my animations in blender. Is there a way to fix this without having to join all the models together or is that the only way?

any suggestions?
