Proper way to name a class which has just methods and not fields

GOAL: naming a class which has the responsibility to save data in Android database. The class structure is like this

ClassName {   public void saveSync(...){      /* implementation*/  }   public void auxiliaryMethod(...){     /* implementation */  } } 

QUESTION: which is the proper manner to name this kind of class? Should I always find a noun or can I use a verb?
