Flex :: Events - Game Communication Between Entities

I'm currently developing a Flex game which is a kind of table and cards game. Thinking about developing other games using entities from this one, I chose for creating my entities decoupled from the game and even from other game entities. As a result, I'm currently using events for communication between my game entities.

Game entities, in my case, refers for example a player hand component which can receive a card, or send a card to another unknown component by a custom requesting and dealing events. For instance, the same can happens to a deck of cards holder component. This approach appeared to be a good designer in the beginning, but after some time, my game controller class has a lot of event handler functions which started looking bad for me.

My current idea is to create a game event manager coupled with my game controller for handling events and cleaning the controllers code. Finally, I'm not sure about my design decision exposed above, so I would like to know about you folks which communication design would be indicated for this kind of a game.
