Problem with Akka Actors that is when you use it, you must use ActorRef Scalatype. It means Akka Actors were not typed. We can "solve" this problem using simpla "companion class" api.

AClassUsingActor.scala

class AClassUsingActor(myClass: MyClass) {
    def useActor = myClass.ref ! message
}    

object CreateActorClass {
    val system = ActorSystem("system")
    val classUsingActor = new AClassUsingActor(new MyClass(system))
    
    classUsingActor.useActor
}

TypedActorViaApi.scala

import akka.actor._

// the class for use specific type instead of ActorRef
class MyClass(val ref: ActorRef) {
    def this(system: ActorSystem) = this(system.actorOf(MyClass.props, MyClass.name))
}

// companion object of Actor for define name & props
object MyClass {
    val name = "myClass"
    def props = Props[MyClassActor]
}

// the Actor
class MyClassActor extends Actor with ActorLogging {
    def receive = ???
}
