Android ViewModelProviderFactory in kotlin

I'm experimenting with the Architecture Components from Google. Specifically I want to implement a ViewModelProvider.Factory to create a ViewModel that takes constructor parameters, like so:

class MyFactory(val handler: Handler) : ViewModelProvider.Factory {
    override fun <T : ViewModel?> create(modelClass: Class<T>?): T {
        return MyViewModel(handler) as T
    }
}

My ViewModel looks like this:

class MyViewModel(val handler: Handler) : ViewModel() 

Anyone knows how to avoid the nasty cast in the end :

return MyViewModel(handler) as T
