(eieio-class-name (make-instance 'my-class))
=>
Debugger entered--Lisp error: (wrong-type-argument eieio--class #<my-class my-class-158f4e54cbbc> class)
  signal(wrong-type-argument (eieio--class #<my-class my-class-158f4e54cbbc> class))
  eieio-class-name(#<my-class my-class-158f4e54cbbc>)
  eval((eieio-class-name (make-instance 'my-class)) t)

On the other hand:

(eieio-object-class-name (make-instance 'my-class))
=> my-class
